省事 (shěng shì) literally combines 省 (to save, reduce) and 事 (matter, affair, trouble), meaning 'to save trouble' or 'to be convenient'. It describes an action, method, or situation that avoids unnecessary effort, complexity, or hassle — often implying practicality and efficiency. Unlike formal terms like 简化 (jiǎn huà, 'to simplify'), 省事 carries a colloquial, everyday tone and is commonly used in spoken Mandarin when evaluating choices or solutions.

This word functions as both an adjective ('convenient') and a verb ('to save trouble'). As an adjective, it typically follows verbs like 是, 比较, or 很; as a verb, it often appears with aspect particles like 了 or 过, or in constructions like 能省事 or 不想省事. It’s frequently heard in domestic, work, or administrative contexts — for example, choosing ready-made food to save cooking time, or using auto-fill forms online.
